BACKGROUND: In this study, we evaluate the association of different clinical profiles, laboratory and genetic biomarkers in patients with sickle cell anemia (SCA) and hemoglobin SC disease (HbSC) in attempt to characterize the sickle cell disease (SCD) genotypes. METHODS: We conducted a cross-sectional study from 2013 to 2014 in 200 SCD individuals (141 with SCA; 59 with HbSC) and analyzed demographic data to characterize the study population. In addition, we determined the association of hematological, biochemical and genetic markers including the β(S)-globin gene haplotypes and the 3...

Cerebrovascular accident (CVA) is a common, devastating neurological complication of sickle cell disorder (SCD) with a high recurrent and mortality rate. The Stroke Prevention Trial in Sickle Cell Anaemia study (STOP) recommends routine screening with transcranial Doppler ultrasonography in children aged two to sixteen years with SCD. The present study assessed cerebral blood flow velocities of children with SCD in accordance with the recommendation of routine screening by the STOP study. METHODS: Transcranial Doppler ultrasonography was done for children with SCD that attended Sickle Cell Foundation, Nigeria between July and November 2015...

The role of the family as the social environment in shaping adolescent lifestyle has recently received substantial attention. This study was focused on investigating the association between familial and parenting predictors and alcohol use in school-aged children. Adolescents aged 13- and 15-year from a representative sample (N = 3715) of schools in Lithuania were surveyed during the spring of 2014. The methodology of the cross-national Health Behaviour in School-aged Children (HBSC) study was applied. HBSC international questionnaires were completed in the classroom anonymously for obtaining information about drinking of alcoholic beverages and family characteristics-family's affluence and structure, style of communication in the family, parenting style, parental monitoring, family time together, etc...

Child abuse is a major public health problem. In order to establish the prevalence of abuse exposure among children, measures need to be age-appropriate, sensitive, reliable and valid. This study aimed to investigate the psychometric properties of the Adverse Childhood Experiences Questionnaire Abuse Short Form (ACE-ASF). The ACE-ASF is an 8-item, retrospective self-report questionnaire measuring lifetime physical, emotional and sexual abuse. Data from a nationally representative sample of 15-year-old, school-going adolescents (n=1733, 55...

Reference values for cerebral blood flow velocity (CBFV) in hemoglobin SC disease (HbSC) have not been established. We aimed to investigate associations between laboratory and genetic biomarkers associated with CBFV in HbSC children. Sixty-eight HbSC children were included; CBFV was analyzed by transcranial Doppler, and the time-averaged maximum mean velocity (TAMMV) was estimated. Hematological, biochemical, immunological, and genetic analyses were performed. TAMMV was negatively correlated with red blood cell count (RBC) count, hemoglobin, hematocrit, and direct bilirubin (DB), yet positively correlated with monocytes and ferritin...

OBJECTIVE: School is a place where students spend most of their daytime hours. Previous studies indicate that the class climate significantly affects students in both positive and negative ways. The aim of our study is to describe the trends in the psychosocial school environment based on four surveyed years in the Czech Republic. METHODS: The trends in perception of school were assessed by the standardised self-reported HBSC questionnaire from data collected in 2002, 2006, 2010, and 2014...

OBJECTIVE: Screen-based behaviours such as watching television or computer use are among the most prevalent sedentary behaviours adolescents spend time on. There is a lack of recent estimates on prevalence and changes in the amount of time spent on screen-based behaviour across Central and Eastern Europe. The main aim is to assess the trends in the prevalence of current recommendations for the screen time (≤2 hours per day) of school-aged children in the Czech Republic between 2002 and 2014...

The Health Behaviour in School-aged Children (HBSC) study is now in its 34th year. It continues to grow not only as a source of reliable and valid data on the health behaviours of 11-, 13- and 15-year-olds, but also regarding its membership - 46 countries and regions across Europe and North America are now included. The HBSC study is a cohort cross-sectional questionnaire-based study focusing on health and health-related behaviours in adolescents in the context of their social environment. This age was selected because of the significant cognitive, psychological, and biological processes taking place in this period of the lifespan, as well as because of the fact that health-related behaviours adopted at this age are known to persist into adulthood...

INTRODUCTION: Sickle cell disease in pregnancy carries a high risk of maternal and fetal adverse outcomes. The use of prophylactic transfusions to reduce the risk of sickle complications is controversial. Current UK standards do not recommend the routine use of transfusion for sickle pregnancy. We examined transfusion episodes during sickle pregnancies in a single centre over an 11-year period. METHODS: We conducted a retrospective observational study of all pregnancies in patients with sickle cell disease who attended the joint obstetric/haematology clinic over an 11-year period...

BACKGROUND: Youth involved with school bullying are vulnerable to many negative outcomes, including substance use. Research has yet to examine how this vulnerability operates in the context of other individual and neighbourhood differences. The current study aimed to fill this gap by using multilevel modeling to investigate both the individual and neighbourhood risk factors associated with frequent drunkenness and frequent cannabis use among adolescents. METHODS: Data from the 2010 Canadian Health Behaviours in School-Aged Children (HBSC) survey were analyzed...

Purpose To describe the reproductive variables associated with different sickle cell disease (SCD) genotypes and the influence of contraceptive methods on acute painful episodes among the women with the homozygous hemoglobin S (HbSS) genotype. Methods A cross-sectional study was conducted between September of 2015 and April of 2016 on 158 women afflicted with SCD admitted to a hematology center in the Northeast of Brazil. The reproduction-associated variables of different SCD genotypes were assessed using the analysis of variance (ANOVA) test to compare means, and the Kruskal-Wallis test to compare medians...

AIMS: The aim of this research was to compare the levels of perceived health literacy among adolescents who do or do not participate in sports club activities. Organized sport club activities reach a high proportion of adolescents, and have the potential to contribute to the development of their health literacy. METHODS: The cross-sectional data on health literacy among school children in Finland (aged 13 and 15, n=3852) were measured, as a part of the Health Behaviour in School-Aged Children (HBSC) study, using the Health Literacy for School-aged Children (HLSAC) instrument...
